$r$ is the number of objects from the total $n$ objects that you want to permute.

For example, if I have the set of characters $\{a,b,c,d\}$ , I can choose to permute any of up to 4 of the characters. Suppose I take just 2 of them. Then the formula predicts I should find ${}_4P_2=\dfrac{4!}{(4-2)!}=\dfrac{24}2=12$ possible permutations. Indeed, these are

$\begin{matrix}ab&ac&ad\\ba&bc&bd\\ca&cb&cd\\da&db&dc\end{matrix}$

The sum of the interior angles of a triangle is 180 the second angle of a triangle is 45 more than the first and the third angle

vfiekz [6]

First angle is x
x + (x + 45) + 2x = 180
4x + 45 = 180
4x = 180 - 45 = 135
x = 135 divided by 4
x = 33.75
first angle 33.75
second angle 78.75
third angle 67.5
checking
33.75 + 78.75 + 67.5 = 180

At the beginning of an environmental study, a forest covered an area of 1500 km. Since then, this area has decreased by 7.25% ea

WITCHER [35]

$\qquad \textit{Amount for Exponential Decay} \\\\ y=P(1 - r)^t\qquad \begin{cases} y=\textit{current amount}\\ P=\textit{initial amount}\dotfill &1500\\ r=rate\to 7.25\%\to \frac{7.25}{100}\dotfill &0.0725\\ t=\textit{elapsed time}\dotfill &t\\ \end{cases} \\\\\\ y=1500(1-0.0725)^t\implies y=1500(0.9275)^t$
